Removing the necessity of providing several different chemical fuels in a series of distinct steps, a novel chemically-fueled molecular motor autonomously produces movement as long as the fuel supply lasts.

Recent research documents a structure-based rational design strategy combining molecular dynamics and single molecule imaging to improve the performance of a DNA tweezers that accurately positions an enzyme and its cofactor.

Combining computational nanotechnology with a noncontact-atomic force microscope probe tipped by a single CO molecule allowed researchers to visualize the dance of individual chemical bonds during a complex organic reaction on a silver surface.

The claim that the recently reported actuating nanotransducers (ANTS) produce forces "orders of magnitude larger than any produced previously" is challenged by a nanocrystal carbon nanotube device reported 11 years ago.

Atomic resolution measurement of quasi-particle tunneling maps of spin-resolved states reveals interference processes that allow simulation of processes important for developing quantum computers based on atomically precise doping of silicon.
